HEN Modern Fuel Demonstration Burns
Texas, Oct 2023
In Oct 2023, HEN Nozzles contracted with West Coast Fire Training (WCFT), Live Fire Acquired (LFA) and LeGear Engineering FD Consulting (Dennis of LEFDC) to coordinate and facilitate demonstration burns using modern fuel packages, these five fires took places in Hillsboro, TX. HEN's internal subject matter experts, Eric Guida and Ray McCormack, meticulously developed and approved each burn plan, in collaborative efforts with the three companies.
A HEN 160GPM@50psi Blade Nozzle was used on all the burns with Chief Kyle Romagus as nozzle operator. All parties assisted in burn designs to ensure that various suppression scenarios were examined safely under very heavy fire conditions these included: a hallway advance, unvented room push, vented room push, multiple room fires, transitional attack, and large area fire.
All of the fire attacks were achieved using the HEN's bladed pattern, this was done to demonstrate its superior characteristics around coverage and extinguishment vs straight of solid streams. The excellent results seen in these videos are related to the Bladed pattern's ability to capture nearly simultaneously floors, walls, ceilings, fuel packages and gas layers. This is based on its unique triangular shape, which produces an instant and continuous large droplet distribution of suppression water within the space with a concentrated edge of critical flow water cooling all surfaces it passes over.
